Multi-Parameter Controller — Kontrol 800
The Kontrol 800 is a dedicated multi-parameter controller for complex applications that require a number of chemical parameters to be checked at the same time. It features independent proportional control outputs, two programmable frequency outputs, an RS485 serial port with Modbus protocol, probe quality checking and data logging. The build listed here (K800L05) measures pH, ORP and conductivity.
